Brain stimulation in Alzheimer disease

Recent studies have reported enhanced performance on specific cognitive tasks in patients with several types of neurological disease, after receiving non invasive brain stimulation (BS), i.e., repetitive Transcranial Magnetic Stimulation (rTMS) or transcranial Direct Current Stimulation (tDCS) to specific cortical areas. In addition, persistent beneficial effects of off-line rTMS on sentence comprehension in Alzheimer disease […]

Effect of memantine on resting state default mode network activity in Alzheimer’s disease

Background: Memantine is an approved symptomatic treatment for moderate to severe Alzheimer’s disease that reduces the excitotoxic effects of hyperactive glutamatergic transmission. However, the exact mechanism of the effect of memantine in Alzheimer’s disease patients is poorly understood. Importantly, the default mode network (DMN), which plays a key role in attention, is hypoactive in Alzheimer’s […]

Improved language performance in Alzheimer disease following brain stimulation

Objectives: Repetitive transcranial magnetic stimulation (rTMS) has been proposed as a possible treatment for the cognitive deficits associated with Alzheimer disease (AD). The aim of this study was to assess the long-term effects, on cognitive performance, of rTMS applied to the left dorsolateral prefrontal cortex (DLPFC) in AD patients.; Methods: Ten AD patients were randomly […]
